Looks really well executed, nice! I'd shared this idea with a few people. GPT and other LLMs don't allow you to use their output to train competing models, but the implication is that it's fine to use their output to train your own internal alternative models. So you can't sell access to the output as an API, but you can use it to replace your GPT API calls. My other thoughts to extend this are that you could make it…
